 WARNING: Always disconnect the battery before servicing high current fuses. WARNING: To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs. |
The front power distribution box is under the front hood. See Under Hood Overview . It has high-current fuses that protect your vehicle’s main electrical systems from overloads. There are also high current fuses next to the front power distribution box. If replacement of these high current fuses is required, see an authorized dealer.If you disconnect and reconnect the battery, you will need to reset some features.
